Slices Allowed?

[Kate32]

Are any kind of slices allowed in Java?

 

[sedj]

Like a slice of pizza ?

[ For those of thus that don't know what a "slice" is ... could you elaborate ]

a slice is a substructure of an array - they are used heavily in fortran

 

[sedj]

Do you mean something like :


Array[] array = { 111, 222, 333, 444 };
Array[] slicedArray = array.slice(1, 3);

And 'slicedArray' now holds '222' and '444' ?

Is that JDK1.5 sedj?

no, its just some 'pseudo code' to see if that is what the OP means (in perl you can do something similar).

Thought you'd found something new there, sedj.

Argh, I had to look up "slice" in the dictionary, you prepotent anglosaxons

Anyway, I'm not aware of such a feature in Java. I guess you need to do it with a for statement.

For Java people: in Fortran, you have an array and you can tell Fortran to print array values from x to y in a single line array(x:y).

But it wouldn`t be that difficult

public static Object[] slice(Object[] originalArray, int begin, int end) {
        if (begin<0 || end>originalArray.length)
            throw new SlicedException("Don't slice me!");
	Object[] slicedArray = new Object[length];
	for ( int i=begin; i<end; i++ ) {
		slicedArray[i-begin] = originalArray[i];
	}
	return slicedArray;
	}

Cheers,
Dian

AbstractList knows a 'subList'-Method:

public List<E> subList(int fromIndex, int toIndex)
